Sendzimir Japan, LTD.

Rolling machines

Higher quality and more accurate products by our better and more precise control technology.
The thin plate cold rolling that is done nowadays requires quality rolling equipment that produces thinner and higher precision plates. We are proud to be known as innovators in the rolling machine industry, and we are always looking ahead for challenging new technical developments. Our precise plate thickness and shape control skills make full use of our intermediate roll shifter and Double Power Crown function, which allow us to meet today's requirements for high quality products based on improved plate thickness and shape precision. That's how we give you more productivity from your manufacturing facilities, and energy savings too. Sendzimir 20 High Mill and Sendzimir Z-High Mill bring these advanced technologies to modern manufacturing facilities.

Sendzimir 20 High Mill
Feature of 20 High Mill:
  • A cluster type configuration of 20 rolls enables to use smaller size work rolls, that allow high reduction rolling of hard metals and the production of thinner gauge strips.
  • The newly developed technologies of Double Power Crown and lateral shifting of 1st intermediate roll are famous for the ability to produce excellent flat surface shape of strip.
  • The high rigidity of zero crown mono-block housing or a pre-stress split housing and high response of hydraulic screw down system realize the production of strip having superior thickness gauge accuracy.
  • Work roll can be easily and quickly changed, as work roll is of simple shape and without chocks and neck bearings.
  • Changing to new work roll at the last pass of a rolling results excellent strip with splendid surface luster.
  • The materials of work rolls can be selected corresponding to the materials being rolled.

Sendzimir Z-High Mill
Feature of Z-High Mill:
  • Rolls are consisting of back-up roll, intermediate roll and smaller work roll supported by a cluster of side support rolls. The smaller work roll enables high reduction, harder and thinner strip rolling.
  • By the functions of lateral shifting and bending of intermediate roll, very flat surface shape of strip can be easily produced.
  • Work roll can be easily and quickly changed, as work roll is simple shape and without chocks and neck bearings.
  • Changing to new work roll at the last pass of a rolling results excellent strip with splendid surface luster.
  • The materials of work rolls can be selected corresponding to the materials being rolled.
  • Easy-to-modify a conventional 4-high or 6-high mill into Z-high mill.
Sendzimir Z-Wiper
Feature of Sendzimir Z-Wiper:
  • Small diameter wiper roll achieves the most efficient strip wiping.
  • Widthwise uniform wiping is realized, because each wiper roll supported by axially divided supporting rollers gives uniform pressing force onto strip.
  • Productivity of the mills is greatly improved, because cleaning or replacing of wiper roll for each coil is not required.
  • The existing wipers can be, easily and in short time, replaced to Z-Wiper, because the space required is quite small.
